Some people really should browse forums for a few minutes before posting such questions.
First of all, there is no even closed alpha yet, it will be started between Feb-March 2014.
Second thing is that there is an announcement made by Bobik here:
if-you-want-to-play-our-game-t385/And also important information here:
for-those-who-still-want-to-support-project-financially-t502/ about donating for project and having a chance to be one of top 100 donators who get instant alpha access.
